No Irish-born person in recent history has had such influence on a president. Power, now 40, moved to the US from Ireland at age 10.

With Hillary Clinton due to step down after Obama’s first term, she would be a live candidate to succeed her if Obama wins re-election.

The Times reported that on Monday night last, Samantha Power took to the podium atColumbia Universityin New York two hours before President Obama was due to address the nation on Libya and received a rock star reception.

Power, who is one of Obama’s key advisers on foreign policy, insisted that Libya was not going to be the main topic of conversation.

“I’m not going to talk much about Libya,” she said, as quoted in The Times.

However, when later questioned she defended the administration’s decision in establishing a no-fly zone, adding failure to do so would have been “extremely chilling, deadly and indeed a stain on our collective conscience.”

Since she began her career working as a war correspondant in Bosnia at the tender age of 22, Power has believed that nations have a moral obligation to prevent genocide. She can bring life to these ideals from her position of the National Security Council.

“She is clearly the foremost voice for human rights within the White House,” Kenneth Roth, executive director of Human Rights Watch, told the New York Times “and she has Obama’s ear.”

Power won a Pulitzer Prize for her 2002 book on genocide, entitled “A Problem from Hell,” which examined the U.S. foreign policy response to genocide.

The book argues that the Armenia, Nazi Germany, Cambodia and Rwanda genocides occurred because of government authorities averted their eyes and individuals made the choice not to intervene.

“The most common response,” Ms. Power wrote, “is, ‘We didn’t know.’ This is not true.”

Some of her critics say that she could be pushing the U.S. into another Iraq. The conservative blog American Thinker says that Obama has “outsourced foreign policy” to the Dublin woman. She has also drawn the ire of the Israeli lobby for her pro-Palestinian positions.

Power attempts to keep a low profile after she described Hillary Rodham Clinton as "a monster" during the 2008 presidential election campaign. Her remarks saw her step down from her position as an advisor on Obama’s campaign. Since then, the women have reconciled.
